Selective Electrochemical Determination of Etoposide Using a Molecularly Imprinted Overoxidized Polypyrrole Coated Glassy Carbon Electrode

Figure 1

Cyclic voltammograms recorded during the formation of the imprinted and nonimprinted polypyrrole films at glassy carbon electrode. Experimental conditions: [pyrrole] = 0.1 M; [ETP] = 3.0×10⁻⁴ M; [NaClO₄] = 0.1 M; number of cyclic scans = 4; scan rate = 100 mVs⁻¹.
